Synopsis ========
A vulnerability in Xpdf might allow local attackers to execute arbitrary code.
Background ==========
Xpdf is a PDF file viewer that runs under the X Window System.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf < 3.02-r2 >= 3.02-r2
Description ===========
Erik Wallin reported that Gentoo's Xpdf attempts to read the "xpdfrc" file from the current working directory if it cannot find a ".xpdfrc" file in the user's home directory. This is caused by a missing definition of the SYSTEM_XPDFRC macro when compiling a repackaged version of Xpdf.
Impact ======
A local attacker could entice a user to run "xpdf" from a directory containing a specially crafted "xpdfrc" file, resulting in the execution of arbitrary code when attempting to, e.g., print a file.
Workaround ==========
Do not run Xpdf from untrusted working directories.
Resolution ==========
All Xpdf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.02-r2"
